Sargasso Sea

The Sargasso Sea is a Gyre in the North Atlantic, permanently rotating in the same area.
It is bordered by the Gulf Stream, the North Atlantic Current, the Canary Current and the North Atlantic Equatorial Current.

The name ‘Sargasso’ is derived from Sargassum, the seaweed that floats in great quantities in this Sea.

As early as the fifth century BCE, the Periplus of Himilco the Carthaginian, described part of the Atlantic as being covered in seaweed. It was referred to by Avienus writing in the fourth century CE.
In 1492 CE Christopher Columbus crossed the Sargasso Sea and commented on the large quantities of seaweed in it.

Aristotle (c.384-322 BCE) was the first to write about eels and guessed that they were born from the earth and not the sea.
The origin of Eels was a mystery in the Ancient World because nobody could ever found young eels.
It wasn’t until the twentieth century that the search was narrowed down to the Sargasso Sea.
Atlantic Eels only reproduce in the salt water of the Sargasso sea. The young then migrate to coastlines carried by the Currents, where they collect in a mass and climb into fresh water streams and rivers. They live there for years, before eventually returning as mature adults to spawn in the Sargasso Sea.
Pacific Eels have similar eel spawning grounds in the Pacific Ocean near the Mariana Islands for the Japanese Eel.
Southern African Eels have spawning grounds in the Indian Ocean north of Madagascar.
